I'd pick 64KHz for sampling rate, too, and maybe try 22.5KHz for the sampling rate ... but whatever you do, RUN A TEST of your entire planned procedure, using maybe just a 1-minute audio clip, to find out if it works well and sounds good to you. If you decide to change a setting, such as bumping sample rate back up to 44.1KHz, then run another short test. In other words, don't do a lot of work that you might regret later. Test first.

I'm guessing that the recordings are quite important to you, so you may want to consider preserving the recordings as is, without editing, in some durable format like CD, before you start editing. Maybe your late Aunt Tootie's constant erm and hrmph sounds annoy you, but her nieces like to hear it because it's a warm and friendly memory of the way Aunt Tootie talked. It'd be great to have the original for such situations -- I think.

No I don't see a problem. In fact I'm going to do just that later this
summer. I'd thing about 44.1k for your sampling rate and 64kbps mono for
your bit rate.

Subject: [Audacity-users] Voice Tapes to MP3 files ??


GREETINGS, ALL

I am a relatively inexperienced Audacity user and I am about to
digitize some old family voice tapes using Audacity 1.2.4 on my Mac.
But I have some questions.

I prowled thru the list archives for the last several months and
picked up some good hints and tips . but everyone seems to be dealing
with music, rather than with voice.

Here is my plan: digitize the old voice tapes, do a light edit on
them to remove long silences and terrible redundancies and false
starts . then export 'em as MP3 files . and burn an archival CD.
Then go thru them again to add explanatory voice inserts or
voiceovers ( to put the 1960s talk in perspective ) and then do a
heavier edit.  I believe it would be best to capture all the stuff in
digital form before my reel to reel tape player dies . and then do
the heavier edit and cleanup . and finally burn CDs for all my
children of the final product.

I understand that MP3s will not play on yesterday's CD players and
that is OK.  I have convinced myself that MP3 will be adequate
quality for the end product . since they are voice tapes NOT music.

The questions;
1. What sampling frequency and bit depth make sense for this voice
application when the final product will be MP3 files ??
2. Are there any important settings in Audacity while saving such a
voice recording as an MP3 ??
3. Does anyone see a problem with this approach ??
